+# 1. Goal
+Check a car damage claim of an insurance company before the company pays it.
+The claims program calls the check for each claim. The check returns the payout
+amount or it stops with a reason.
+
+# 2. Open questions
+None.
+
+# 3. Context
+- The exception class {{P}}CX_CLAIM_ERROR exists in package $TMP. It is active.
+- The class inherits from CX_STATIC_CHECK.
+- The class has the public type TY_REASON (CHAR 12) and the read-only attribute
+  MV_REASON of type TY_REASON.
+- The constructor of the class has the importing parameter IV_REASON of type
+  TY_REASON.
+- The class redefines GET_TEXT. The text of the exception contains the reason.
+
+# 4. Contract
+- Create the class {{P}}CLAIM_CHECKER in package $TMP.
+- The class is public, final, and has a public constructor without parameters.
+- Public types of the class:
+  - TY_POLICY_ID TYPE c LENGTH 10.
+  - TY_AMOUNT TYPE p LENGTH 8 DECIMALS 2.
+  - TY_CLAIM, a structure with the components POLICY_ID (type TY_POLICY_ID),
+    VEHICLE_AGE (type i), DAMAGE (type TY_AMOUNT), DEDUCTIBLE (type TY_AMOUNT),
+    REPORT_DAYS (type i) and PHOTO_COUNT (type i).
+- The public constant C_MAX_PAYOUT TYPE TY_AMOUNT has the value 10000.00.
+- One public method:
+  CHECK_CLAIM
+    IMPORTING is_claim TYPE ty_claim
+    RETURNING VALUE(rv_payout) TYPE ty_amount
+    RAISING {{P}}CX_CLAIM_ERROR.
+- Do not add other public methods.
+
+# 5. Business rules
+Apply the rules in this sequence. Raise the exception {{P}}CX_CLAIM_ERROR with
+the reason of the first rule that fails. The reason is the text that the rule
+shows.
+1. The policy ID must start with the letter P. The other 9 characters must be
+   digits. Else raise the reason 'POLICY'.
+2. REPORT_DAYS must be between 0 and 14. Else raise the reason 'LATE'.
+3. VEHICLE_AGE must be between 0 and 12. Else raise the reason 'AGED'.
+4. PHOTO_COUNT must be at least 2. Else raise the reason 'PHOTOS'.
+5. DAMAGE must be greater than 0. Else raise the reason 'DAMAGE'.
+6. DEDUCTIBLE must be between 0 and DAMAGE. Else raise the reason 'DEDUCT'.
+7. The payout is DAMAGE minus DEDUCTIBLE.
+8. If the payout is greater than C_MAX_PAYOUT, the payout is C_MAX_PAYOUT.
+
+# 6. Constraints
+- Release target: 8.16.
+- Coding standards: Clean ABAP. Method length below 40 statements. No global
+  variables. No comment that restates the code.
+- Out of scope: do not change {{P}}CX_CLAIM_ERROR.
+
+# 7. Acceptance
+- The class is active and has no syntax error.
+- The hidden tests pass.
+- Write your own ABAP Unit tests for the class.
